Comprehensive Study on Quantitative Evaluation of Oral Muscle Tissue in Children With Low Tongue Posture Using Cone Beam Computed Tomography: A Comprehensive Study on Nasal Ventilation Conditions Using Computational Fluid Dynamics

Journal of Oral Rehabilitation, EarlyView.
Measurement of nasal airway computed fluid dynamics, muscle‐fat tissue analysis in this study. Four typical examples illustrating the relationship between low tongue posture, nasal ventilation condition, and perioral muscle‐fat tissue are demonstrated in this study. A.

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

G1 continuous surface approximation to generalized Bézier surfaces(广义Bézier曲面的G1连续曲面逼近)

Zhejiang Daxue xuebao. Lixue ban
Generalized Bézier (GB) surface is a new N-sided surface. This kind of surfaces are generalizations of tensor product Bézier surfaces and have simple control meshes and good geometric properties as well.

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

AIChE Journal, Volume 72, Issue 6, June 2026.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

Viscoplastic Modeling the Evolving Mechanical Properties of Shotcrete 3D Printing Material

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT In recent years, additive manufacturing in construction (AMC) has gradually influenced the building industry by offering a faster and more efficient way to build with concrete. Unlike traditional methods that rely on molds, AMC deposits material layer by layer through an automated process, enabling new possibilities for custom designs and ...

An Efficient Geometrically‐Exact Nonlinear Shell Formulation Based on Rodrigues Parameters

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Thin‐walled structures are part of many engineering applications, as wind turbine blades, pressure vessels, and sheet metal products. A thin‐walled structure is characterized by one significantly smaller dimension compared to the others.

Block‐Structured Meshing in Coupled Problems With Moving Domains

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Structured mesh generation is a delicate task in (multi‐physics) simulations on moving domains. For a given geometry, such meshes may be generated based on a block‐structure: This is a coarse‐scale representation of the geometry using blocks with the exact geometry and desired grading information assigned to the block edges. Based on the block‐

Stabilized Finite Elements for Incompressible, Stationary Navier–Stokes Flows on Manifolds

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT A surface finite element method with residual‐based stabilization for stationary Navier–Stokes flows on curved manifolds is introduced. The mixed formulation in stress‐divergence form leads to a system of equations that has a saddle‐point structure.

Multi‐Goal‐Oriented Anisotropic Error Control and Mesh Adaptivity for Time‐Dependent Convection‐Dominated Problems

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT In this work, we present an anisotropic multi‐goal error control based on the dual weighted residual (DWR) method for time‐dependent convection–diffusion–reaction (CDR) equations. Motivated by former work, we combine multiple goals to single error functionals with weights chosen as algorithmic parameters.
